DOORSTOP.

Application filed July 26, 1922. Serial No. 577,508.

To all whom itEmay concern:

Bait-known that we, RICHARD H. BURR- GER and ALFRED J. SoHULz, citizensof the United States, residing at Milwaukee, county of Milwaukee, andState of Wisconsin, have invented new and useful Improvements inDoorstops, of which the following is a specification.

This invention relates to improvements in door stops. i

-' The device hereinafter to be disclosed is particularly adapted foruse in connection nvith garage or barn doors or the like.

It is the object of this invention to roride a door stop ofnovelconstruction w ich can be cheaply manufactured, readily applied, andeasily operated. It is a further object of this invention .to provide,without adding materially to the ex ense A of manufacture, convenientmeans or supporting the stop in an out of i the way position at suchtimes as, it is not in use. I

In the drawings:

Fig. 1 is a perspective view of the front of the garage showing theimproved door stop applied to each of the doors.

. Fig. 2.is a front elevation of the device in its operative position.

Fig. 3 is a side elevation of the device in its inoperative positionwith a portion. broken away to expose the preferred construction.

Fig. 4 is a section taken on line 4-4 of as Fig. 3.

, Like parts are identified by the same reference characters throughoutthe several views.

'The garage 10 is supphed with swinging to doors-11 and 12 to each ofwhich a door stop embodying this invention is shown to be applied. -Thisdevice is particularly adapted for use upon garage doors not onlybecause itwi-ll hold such doors efiectively against displacement by thehigh wind ressures to which the relatively large sur aces of such doorsare subjected, but also by reason of the fact that a stop of the kindhereinafterto he described is operative either upon the earth or upon apavement, whether the surface of the earth or pavement lies closelyadjacentthebottom ot the door or whether it slopes-away from the garagein. such a manner "that it will, at some ints, be a considerabledistance below the ttom of the door. It constitutes a peculiar problemthat ordinarily the approach to a garage is upwardly inclined so thatthe distance between the lower margin of the door at its outer end andthe earth varies according to the extent to which the door is open. Thestop hereinafter to be disclosed is so constructed as to be operative toprevent the door from closing Whether the distance between the doorv andthe earth be great or small within the range of o eration ofthe stop. Apair of flanged p ates 13 and 14 are provided with openings 15 throughwhich screws may be passed to secure the plates to the lower ortions ofa door with their outwardly rogectin flanges 16 and 17 in a substantialy para lel relationas shown. A rivet, or bolt, 18 connects the flanges16 and 17 of plates 13 and 14;, respectively, and serves as a pivot "foran eye 19 which is formed in the end of a rod 20 which constitutes thedoor stop proper. The flanges 16 and 17 are so spaced as to receive andconfine the eye 19 and the rod 20 closely between them, whereby theselatter elements are secured a ainst lateral displacement relative to theanged plates. The lower extremity 21 of rod 20 is ref erably cut offsquarely in the manner mdicated in Fig. 2,whereby the margins of the endportion 21 are reasonably sharp and are well adapted to engage thesurface of a pavement such as is shown at 22 in front of arage 10 toprevent the doors from swinging shut. The rod 20 of the device shownattached to door 12 in Fig. 1 is illustrated in its operative positionof engagement with the pavement.

For the purpose of supporting rod 20 in an inoperative positionillustrated in the full line positions thereof in Figs. 1 and 3, theflanged lates 16 and 17 are made slightly resilient and a protuberance24 is formed in one of the flanges 16 or 17 and is adapted to projectinwardly into the space between said flanges to materially decrease thedistance between them at this point. The arrangement is such that whenthe rod 20 is swung upwardly rivet, or pin, 18 as a pivot, it willencounter the protuberance 2t and will have to force the flange 16outwardly in order to pass position in the manner clearly shown in aboutthe will llild I Fig. 3. The position of protuberance 24:

is carefully calculated with reference to the length of rod so that anintermediate portion of, the rod will remain in contact with the(protuberance at the time when the upper en 21 of the rod contacts withthe I ad acent plane surface 25 of the door. This that the devicedisclosed herein satisfies the several objects specified for thisinvention in that it may be cheaply manufactured and easily operated,and is capable of satisfactory performance under all of the variousconditions noted above.

We claim;

1. A door stop including a pair of plates connected by a transversemember and maintained in substantial'parallelism thereby, one of saidplates being formed of resilient material and being provided at a pointremote from said transverse member with an integral protuberanceextending in the direction of the other of .said plates, laterallyextending flanges integrally attached to the margins of said plates andapertured to receive securing screws, and a brace rod pivotally movableabout said transverse member and engageable in one position behind saidprotuberance.

2. A door stop including a pair of plates connected by a transversemember and maintained in substantial parallelism thereby, one ofsaid'plates being formed of resilient material and being provided at apoint remote from said transverse member -with an integral protuberanceextending in the direction of the other of said lates, laterallyextending 'flanges integrally attached to the margins of said plates andapertured to receive securing screws, a brace rod ivotally movable aboutsaid transverse mem r and engageable in one position behind saidprotuberance, said' rod being formed with an integral eye in one end toreceive said transverse member. Y

3. A door stop including a pair of flanged plates connected by atransverse member and adapted to be secured in spaced relation upon adoor, one of said plates having an inwardly projecting protuberanceremote from said transverse member, and a rod ,hingedly mounted uponsaid member and adapted in one position to be engaged behind saidprotuberance, the positions of said, member and'of said protuberance andthe length of the rod being such that when said rod is engaged itsextremity will lie substantially in a plane including the flanges ofsaidplates.
